+4 = 2 BE (refining value 1.5k-3kk)

+10 = 25 BE (refining value 200kk-300kk including luck/attempts/rare/one of kind)

Some weapons like highly refined GBWD Bracers can be more expensice than other GBWD weapons due to their high demand. Like +8 GBWD Bracer is about 120kk-140kk. Less demanded weapons are for example all SMWD and less popular one-role weapons like dagger and axe. 4 clans uses gloves(healer-hyb) and all 6 clans uses bracers(nuker), so there is more people demanding them.
